MARTE 2.0 RFI (OMGページ)に RFI のドキュメントと Response list があります．
RFI ドキュメントに記載の Summary of this RFI では
Our goal is to modernize, enhance and integrate the embedded hardware and software model-based design and analysis frameworks that are enabled by MARTE with the opportunities that heavily distributed and intensive communication run time environments as well as other modern technologies offer nowadays. Since the inception of MARTE, 12 years ago, a number of OMG standards have emerged to improve the UML base semantics, and additional new analysis and design techniques as well as application domains (e.g., IoT and AI) for MARTE have appeared. Then, to drive the update of the language over the basis of the updated UML and its related standards, it is time to seek inputs from the community for potential enhancements and additions in the various domains in which MARTE could be used, and to account new design and analysis techniques that emerged in the meantime.
とのことです．The purpose of this RFI is to identify the community of interest and to identify potential stakeholders, along with their specific interests and needs. These will be used to prepare a roadmap for MARTE evolution and more specifically concrete requirements for MARTE 2.0.
